' TYPOGRAPHICAL MACHINE LINE INDICATOR Filed May 14, 1937 Patented Apr. 11, 1939 "T UNTTED STATES PATENT orrlee TYPOGRAPHICAL MACHINE LINE INDICATOR Glen F. Gale, Salt Lake City, Utah Application May 14, 1937, Serial No. 142,526

3 Claims.

My invention relates to attachments for typographical machines such'as are called Linotype machines and has for its object to provide a new and eflicient indicator for indicating on which end of the line the operator is working when he is setting up a butted up or twin slug job.

A still further object is to save the time for the typesetter by automatically recording on V which end of the line he is working when he is setting up twin slug jobs.

A still further object is to provide an automatic recording device for indicating which end of the "line the typesetter is working by the movement of the assembling elevator actuating the indicator and rotating the disc wheel one half turn with each upward movement of the elevator.

These objects I accomplish with the device illustrated in the accompanying drawing in which similar numerals and letters of reference indicate like parts throughout the several views and as described in the specification forming a part of this application and pointed out in the appended claims.

In the drawing in which I have shown my device Figure 1 is a .view of part of the assembling elevator with my indicator mounted to be actuated thereby.

Figure 2 is a face View of the indicator.

Figure 3 is an edge view of the indicator.

Figure 4 is a section on line 4-4 of Figure 3.

Figure 5 is a face view of the indicator dial.

' Figure 6 is a rear View of Figure 5.

Figure '7 is an end view of the operating finger iorrotating the dial when the elevator is operated.

Figure 8 is a side view of Figure 7. I In the drawing I have shown the support body bracket forthe indicator as A, the indicator dial or disc as B and the operating finger as C. The assembling elevator of the type machine is shown as D and in Figure 1 only part of this is shown as there is no need of showing more, the only part shown being the part on which the operating finger is secured. Thebody bracket A is provided with two ears 5 and 6 on opposite sides thereof by which it is secured to the body of the type machine by suitable screws or stud bolts. One end of the body A is bent forward and then back parallel thereto to form the face I forming a U-shaped channel 8 therebetween. Within this channel the operating parts of my device are mounted. The indicating dial Bis secured to this face I by a stud bolt 9 being passed into a socket l4 through a suitable hole near the end of the 455 face I and through the central hole of the dial D. The face of the dial D is provided with two letters R shown at in and fL shown at H. these two indicating letters being to indicate to the operator whether he is working on the right or left side of the twin slug job.

On the back side of the dial B I provide inwardly extended spaced apart diametrically opposite pins l2 and i3 secured in the dial B and extended inwardly to provide a means for turn ing the dial B. A spring control arm I4 is pivotally mounted to the back of the body A by a stud bolt l5 acting as the pivot pin therefor and the end of the arm is extended a short distance and a control spring I6 is attached thereto with the other end of the spring attached to near the bottom of the body A by a boss or lug ll. The face of the lever is adapted to engage the two pins l2 and I3 and hold the dial B in indicating position until the pins are engaged and rotated by the finger C. This finger C is attached to the elevator D by a screw 21 and when desired a spring may be placed between the head of the screw and the vertical body of the finger to hold it in tension position, or allow for partial rotation of the finger on the screw to move it from engaging the pins 12 or l3 when it is being operated in case the operator is not setting up a twin slug or butted up job. This finger C has the engaging. finger 2U bent out at right angles to the main body and has the top side formed on a slope to allow the elevator to raise with the slanting surface engaging the pins one at a time and cause the dial to rotate, the slant being to eliminate friction and allow the dial or disc B to rotate freely.

The operation of the device is obvious but for clarity I will state that with each formation of a slug the dial is turned one half turn and the next slug turns it the next half turn to the point of beginning so that the operator knows at all times whether he is operating on the right or left hand of the twin slug set up of the type. When it is not in use the finger may be disengaged from the vertical alignment with the pins 12 or 13 and the elevator will operate without operating the dial. When the finger 20 travels down with the assembling elevator it engages one of the pins l2 or it and having a flat lower edge the finger presses down on the pin sufficient distance to cause the plate or dial to rotate being in a position that the spring control arm It has passed beyond the upward tension of the spring but the instant that the dial has rotated the spring brings the arm l4 back to normal position preventing further rotation of the dial. When the finger is traveling upward with the assembling elevator the top side of the finger, being cut on a slope, engages the respective pin but merely slides around it partially turning the dial in reverse direction but not sufiicient distance to rotate it sufiicient to turn it in the reverse direction.

Having thus described my invention I desire to secure by Letters Patent and claim:

1. In a device of the class described the combination of a body bracket to be secured stationary to the typographical machine; a rotatable dial mounted in a channel in said body; pins extended from said dial; means to hold said dial in rotatable but spring held position; and means to engage said pins to rotate said dial. with each operation of the assembling elevator of the typographical machine.

2. In a twin slug indicator for typographical machines the combination of a fiat dial having indicating figures printed on the face thereof one of which may be read and the other being upside down until the dial has been rotated one half turn; a finger mounted to the assembly elevator of the machine; means on said dial to be engaged by said finger to partially rotate said dial with each movement of said elevator; and a bracket in which said dial is rotatably mounted a portion of said bracket covering the figure on the dial which is upside down to the operator.

3. A line indicator for typographical machines to indicate the side of the line on which the operator is typing comprising a flat dial having figures visible on the face thereof one of which is right-side up and the other of which is upside down; a bracket in which said dial is mounted to said machine said bracket having one portion extending over the greater portion of the exposed face of said dial to cover all but the readable figure thereon, and means to partially rotate said dial one half turn with each operation of the assembly elevator of the typographical machine.
